Hi ! I try to read data in ADA from input register (pins: 10,11,12,13,15) of LPT port and I can't do this :-(, with using a handle and function CreateFile(), and then ReadFile() from Win32.Winbase. The connection is probably made, but register is located in memmory address 379h, and I can't get there :-( I know that way it can be read from COM port, but can I make it with the LPT port too??? I don't know if I can do it with this functions CreateFile and ReadFile from library Win32.Winbase. Maybe someone help me with LPT ?!? ;-( maybe someone help me and send me a few lines of code? ;-) PS Please, forgive me my English :/ S�awo - MIR
